In order to handle per-layer frame dropping both VP9 encoder wrapper and RTP packetizer were modified. - Encoder wrapper buffers last encoded frame and passes it to packetizer after frame of next layer is encoded or encoding of superframe is finished. - Encoder wrapper sets end_of_superframe flag on last encoded frame of superframe before passing it to packetizer. - If end_of_superframe is True then packetizer sets marker bit on last packet of frame.
